“Breathing Technique?”

Hearing Chika’s words, Nezuko was slightly stunned at first, then her eyes sparkled with intense light.

Even a little cutie like Nezuko had them.

Moreover, seeing Chika and Tanjirou sparring with swords in the morning had ignited this desire in her heart even more.

“B-but…

can I really learn it?

Can I actually master it?” Nezuko asked softly, lowering her head with a lack of confidence.

“Of course you can!

If both of us can learn it, there’s no reason you can’t, Nezuko.

Right, Tanjirou?” Chika said, turning her head to look at Tanjirou.

Seeing Chika pass the ‘microphone’ to him, Tanjirou quickly continued, “Of course!

Nezuko can definitely do it too!”

How could Tanjirou possibly disagree with giving Nezuko more means to protect herself?

Listening to their words, Nezuko was so happy her eyes turned into little dots, and she spun around in place.

At that very moment, in the living room of the log cabin, Urokodaki was still sitting quietly in his seat, waiting for them to join.

“They’re so slow…”

Ten minutes later, Chika and the others finally arrived in the living room.

Even though Urokodaki still wore his tengu mask, they could feel the intense aura of dissatisfaction emanating from him.

It was as if his aura was saying, ‘How can you be so dawdling?

The food is getting cold, you know?’

Chika and Tanjirou awkwardly lowered their heads.

Among them, Chika’s feelings were the most complex, because she remembered she had once said something similar at home.

Then, Chika and Tanjirou told Urokodaki about their idea of having Nezuko learn a Breathing Technique.

Urokodaki, who had just lifted his mask slightly, revealing half his face to drink miso soup, froze on the spot, nearly spraying the soup from his mouth.

A demon…

learning a Breathing Technique?

A demon’s physical constitution and regenerative abilities far surpass those of humans.

Humans can fight demons relying on nichirin blades and Breathing Techniques.

But a demon learning a Breathing Technique?

Urokodaki had never thought of this point and had never seen any demon use a Breathing Technique.

At that moment, two thoughts flashed through Urokodaki’s mind.

One: Can a demon truly master a Breathing Technique? This story is hosted at g.com.

Two: How powerful would a demon be after mastering a Breathing Technique?

“Perhaps…

we can give it a try.”

After some thought, Urokodaki agreed with their idea and was even quite interested in it.

Nezuko, learning a Breathing Technique with her demon body!

After finishing lunch, Urokodaki began personally teaching Nezuko Water Breathing.

When it came to teaching, it was best for Urokodaki to take charge himself.

Because Nezuko was a demon, she couldn’t practice in the open area outside and could only learn inside the house.

During this learning process, Urokodaki repeatedly expressed that he finally felt like he was teaching a normal student again.

Nezuko had no foundation in swordsmanship at all.

Moreover, due to her demon body, she required long periods of sleep, making it impossible for her to study for extended durations.

However, Nezuko’s willingness to learn was very high, so her progress wasn’t particularly slow either.

Half a month later.

A man wearing a bamboo hat walked step by step from the distance.

At that moment, Chika and Tanjirou were sparring, so they were outside.

“Wait a moment, it seems someone is coming.”

“Someone?

Who…

Could it be that the nichirin blades are finally ready?!” Tanjirou exclaimed excitedly, immediately turning his head to look in the direction Chika was gazing.

They saw the approaching man was not only wearing a bamboo hat but also a strange mask on his face.

Looking at this mask, both of them immediately thought of the mask Urokodaki wore, silently marveling at how much more aesthetically pleasing their master’s mask was.

Of course, Criticism, Tanjirou still politely hurried over to greet this delivery person.

“Excuse me, are you here to deliver the blades?”

Tanjirou asked politely.

The person stopped walking and nodded.

His name was Haganezuka, a craftsman who forged nichirin blades.

On his back were two cloth-wrapped rods, inside which lay Chika and Tanjirou’s nichirin blades.

Tanjirou happily invited Haganezuka into the house.

Haganezuka took off the two cloth-wrapped rods from his back and unwrapped them, handing the two original versions of the nichirin blades to Chika and Tanjirou respectively.

“Looking at the color of you siblings’ eyes and hair, you must come from a family associated with fire.

In that case, your blades might very well turn red.

How exciting,” Haganezuka said expectantly, crossing his arms.

Hearing this, Chika’s eyebrow visibly twitched, and her calm expression slightly cracked.

“That’s not necessarily true.

The probability of their blades awakening to blue is also very high,” Urokodaki, sitting properly beside them, said seriously.

nichirin blades are also called color-changing blades.

These blades change color according to their owner.

Factors influencing the color change could be personality or family background, but the highest probability is synchronization with the representative color of the Breathing Technique learned.

Water Breathing is “azure blue.”

Flame Breathing is “fiery red.”

Wind Breathing is “verdant green.”

Stone Breathing is “earthy gray.”

Thunder Breathing is “golden light.”

Under the watchful eyes of Urokodaki and Haganezuka, the two began the color change of their nichirin blades.

The nichirin blade in Tanjirou’s hand turned black under everyone’s gaze, and both men’s eyes showed expressions of surprise.

“Bl-black!”

“What an unexpected change…”

In the history of the last few hundred years, no wielder of a black blade has become famous.

Forget about the top-tier “Hashira,” not even swordsmen of the “Kinoe” or “Kinoto” ranks have emerged from them.

Most have lost their lives in battles with demons.

Facing their unusual gazes, Tanjirou looked at the black blade in his hand without any dislike.

He felt this black blade suited his taste perfectly.

After Tanjirou’s color change, everyone turned their gaze to Chika.

Thinking that if Tanjirou’s was black, Chika’s might also be black, under everyone’s watchful eyes, the nichirin blade in Chika’s hand changed to a color that surprised everyone, including herself.

Blue!

A very clear, pure blue, making one marvel at how beautiful this blade was.

This was one of the two normal expected answers.

Both Urokodaki and Haganezuka breathed a sigh of relief.

For a Water Breathing user, blue was normal.

Only Tanjirou and Chika were still surprised, especially Chika.

She looked at the blue blade in her hand, her eyes slightly furrowed.

Why?

Why is my blade blue?

Could it be that my compatibility with Hinokami Kagura isn’t high?

Does heaven think I should properly follow the path of Water Breathing?

This…

is really too strange.
